UNITED STATES HENRY corn, on DENV COLORADO- WATER-ELEVATOR.

Specification of Letters Patent,

Application filed'May 29, 1905. Serial No. 262,882.

To a whom it may concern.-

Be it known that l, HENRY COLE, a citizen provements in Water-Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and f1 ures of refer ence marked thereon, which 'orm a part of this specification.

My invention relates to improvements in water-elevators, my object being to provide a cheap and efficient means of raising water for irrigating and other purposes.

It is well known that a cheap and efficient water-elevating device would be valuable for irrigating purposes in those districts, which are numerous, where there is plenty of water located only a few feet below thelevel of the ground where the irrigation is required. My improved device is intended for this work. It also may be used to advantage in raising water from considerable depths, if desired.

The invention consists of an endless carrier composed of two flexible devices, as chains, connected by buckets, which are adapted to pass through a body of water, whereby they become filled. The construction of the top of the apparatus is such that the buckets are automatically dumped by a rolling action.

Having briefly. outlined my improved construction, as well as the function it is intended to perform, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a view of my improved device when in position for use. Fig. 2 is a view taken at right angles to Fig. 1. Fig. 3 is a fragmentary view of the same mechanism, shown on a larger scale. Fig. 4 is a fragmentary view showing a detail of construction. Fig. 5 is a fragmentary view of the upper part of the apparatus. Fig. 6 is a view illustratinga modified form of construction.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate each of two endless sprocket-chains engaging two pairs of upper sprocket-wheels and two pairs of lower sprocket-wheels 6. These chains are connected by buckets 7, whose extremities are provided with spindles 8,, journaled in the chains. Each bucket is open at the top, as shown at 9, whereby it normally has a tendency to assume the upright position, or the position with the opening 9 uppermost, since the material of the bucket is cut out to form this opening, thus making the device lighter above than below the horizontal center.

The upper and lower pairs of sprocket wheels are journaled in a suitable frame composed of upper and lower parts 10 and 12 andupright posts 13. Motion is transmitted to the endless carrier by connecting a pulley 14 with any suitable power. This pulley is mounted on a shaft 15, to which is made fast a gear 16, meshing with a larger gear 17, fast on a shaft 18, to which two of the upper sprocket-wheels 6 are made fast. A second s aft 18 carries the other two sprocket-wheels 6'. The upper part of the framework 10 is provided with a track 19, adapted to engage the exterior surface of the bucket 7, causing them to roll sufficiently to assume the dumping position or-to discharge their contents through their openings 9. Attention is called to the fact that the buckets are of cylindrical shape, whereby as they engage the tracks 19, one on each side, they roll until they are in position to discharge their contents. Each bucket is provided at each end with a pinor projection 20, which is adapted to engage a stop-plate 21, which Iprojects above the track and is somewhat s orter than the latter. The pins engage the said stop-plates as soon as the buckets have rolled to the dumping 'position,or that shown at the top of Fig. 3.

After'the ins engage these plates the buck- Patented Nov. 27, 1906.

ets slide a ong on the tracks 19 until the pins 20 reach the extremities of the sto -plates.

It is now assumed that the buc ets .are

empty, and they may either turn over and assume the upright position or assume the same position without turning over, according to the details of construction. In other words, the pins 20 disengage the stopplates before the cylindrical surfaces of the buckets are released from the tracks 19 the tendency would be for the friction between the tracks and the buckets to turn the latter over, whereas if the pins should disengage the stop-plates at the same moment that the cylindrical surfaces of the buckets leave the tracks 19 the tendency would be for the buckets to assume the upright position by moving in the direction of the arrow -.shownat the upper part of Fig. 2.

After the buckets have left the track and are moving downwardly on one side it is desirable before theycome in contact with .the .water A that they should assume a reversed.

position in order to allow the water to enter them, andthus avoid the resistance due to the buoyancy resulting from an attempt to force theempty bucketsinto thewater. In order to. accomplish this object, a friction-plate 21 ismounted on the frame, Whichthe' cylindrical surfaces of the .buckets are adapted to engage justv before they enter the water, wherebythebucketsare rolled sufficiently to.

cause them to .assu-mea position partly in.-

vertedas they enter the water inlsuch a manner that the dipping action maybe easily acc'omplishedthat. is to say, when the bucket. first begins to fill, the mouth is partly exposedto the atmosphere, thus allowing the.

air within. the bucket to. escape as the water enters. This operation may-be so regulated thattheairwill be practicallyv all out of .the

bucket before; the. latter is completelyimmersed,

In the form of construction shown in Fig. 6 it is assumed that a pair.-of;wheels.23.are. mounted onan axle 24. andengagedbyra pair I of. flexible, devices. 25, carrying buckets 26.;

The. gravity of the wheels23 is assumed tobe. sufficient to, cause the bucketsto. enterthe water. Under this arrangement vtherewould beftwo wheels only atthe bottom. of .theap:v

paratus, while there would be four at theupper. part thereof, as illustrated in Figs. 1, .2,

idea. that the bucketsmay be caused to. enter the water by a pair of wheels supported only by the endless carrier.

From theforegoing description the use and.

operationof my improved apparatus will'be readily understood. Assuming that the ap..

paratusisin the. position shown in Figs. 1, 2,

and 3,, if 'powenis transmitted tothe endlesscarrier. in. the manner heretofore explained I the filled bucketsas they first rise to. the top gin todischargetheir contents into a suitable receptacle B1. Now as soonv as they have.

' maininnthispositionlong enoughto completelydischargetheir contents the pins 20 ontheir extremities engage, the stop-plates. .65

ofthe apparatus will be in the upright posi- .tion., Now as these buckets. pass to the: tracks 19anden agethe latter theybegin to.

roll-on thesetrac s, and-as they roll they be reached thedumping position in order tore- 21, whereby further rolling action of the buckets is prevented, causing them to slide along on their tracks until their contents are completely discharged.

Having thus described my invention, what I claim is 1; In a water-elevator, the combination of endlessflexible devices, buckets whose. opposite. extremities are journaled in said devices,

a track located at the upper part of the apparatus and arranged in the path of and adapt 7 5 ed to. engage. the outer curved surface of the buckets... causing the latter to roll to the dumping position, theexterior surface of the bucketsbeing curved to facilitate the rolling action.

2. In a water-elevator, the. combination of. an endless carrier composed of flexible devices, and bucketsournaled in said devices, the buckets having curved exterior surfaces, a track located atthedumping-te'rminal of 8 the; apparatus. and. arranged .in' the path of and adapted .to engage theexterior surfaces of the buckets causing them to roll to the. dumping position.

3,. .An endless carrier provided with cylindrical buckets, a track mounted at the dumping-terminalof the apparatus and adapted to engage the exterior surfaces of the buckets whereby. the. latter. are adapted to roll to. the dumpingposition, andlmeans for. limitin the. rolling action of thebuck'etsafter they have reached a predetermined limit, substantially as described; and for the purpose set forth.

4. A waterselevator. consisting of anendlesscarrier provided with cylindrical buckets open at .the top, a track located at the dumpingsterminal of the apparatus and adapted-to engage, the buckets-and cause the latter to roll to the dumping position, each bucket having a pin, and a stop mounted inthe .path of the pin whereby therolling action of the bucket is checked ata predetermined point, substantially as. described.

5. An endless water-elevator composedof two endless. devices andcylindrical. buckets connecting. the endless devices, the buckets being, jo'urn-aled at their extremities. in the flexible devices, wheels engaging the flexible devices and: supporting. the carrier, means connected with. the lower part of the carrier for causing. thebuckets-to. enter a body of water at their downward limit, means .located at the upperterminal of theapparatus for. engaging the exterior surface of the buckets whereby the resulting frictioncauses the buckets to roll to the dumping position, and means for limiting the rolling action of the buckets, substantially as described.-

In testimony whereof I affix mysignatureinpresence of two witnesses.
